Hello, thank you for visiting this website.

I'm licensed radio amateur since 1978 when passed exam at the age of 18. My favorite mode is traditional CW (not computer decoded) on hf bands and DX.

Although good old fashioned CW is my most favorite mode, I'm active in many other modes on HF bands, VHF and satellites. Homebrewing is part of the hobby here.

I enjoy rag chewing and paper qsl cards.

Profession is electronics engineer in the field of EMC and RF. Own a RF company for more than 25 years which manufactures RF measuring equipment for the industry and space components for orbiting satellites.

For me, mastering CW still remains an essential skill for any serious shortwave radio amateur.

XYL Christiane and I have our home in a little village called Grossmuss, which is located in the Bavarian district of Lower Bavaria, only a few miles south-west of the beau
tiful ancient city of Regensburg.

Regensburg has a 2400 years old Celtic, Roman and Bavarian history. Today, Regensburg is one of the oldest German cities and "World Heritage".

If you are currently watching my QRZ account because of our recent QSO on 40m or 80m, than you possibly might be interested which rig I operate. This is the amateur radio rig I most likely used for our QSO on 40m or 80m (sometimes on other classic ham radio bands, too). It's a classic.

Yaesu/Sommerkamp F-Line. RX = FR-100B made 1965, TX = FL-200B made 1967.
This rig is completely made of vacuum tubes, no transistors. Only a couple of ancient diodes as semiconductors. RF PA tubes are genuine Beam Deflection Power Tubes type Sylvania 6JS6A. RF output is up to 150 watts RF. I usually use about 50 watts output to keep the signal as clean as possible and to spare the PA tubes. The rig has a free running tube VFO (12AT7=ECC81) therefore I apologize for a little QRH.

I use a U.S. made Vibroplex Blue Racer bug or a German Luftwaffe T.2. Telefunken straight key made 1943 with that rig. Headphones are high impedance EPREES 2000 ohms made 1944. My antenna is a 2x14m doublet up about 10m over ground. It is feeded through a balanced 600 ohms line which is guided into the shack. I use a homebrew balanced kilowatt tuner with roller inductors.

I hope you enjoyed the classic sound of the 60's from me today.

Regensburg City.

The ancient city of Regensburg is located close to our small village where we live since June 2016.

My dachshund Wasti.

Wasti loves CW.

Whenever he hears the Vibroplex swinging the dog enters the shack to take his seat.

View into my shack.

Most of my ham radio equipment is from the 80's and 90's. I like those boat anchors. Operate it means joy for me.

Way back made YAESU transceivers are my favorites. FT-1000MP, FT-990 and FT-847 are in my shack.

HF linear amp is a Kenwood TL-922.

I am a DXLab user.

German Telegraphy Club.

AGCW-DL is Germany's most important and greatest CW club. The club counts more than 2.300 national and international members.

AGCW-DL is open for everyone who is interested in CW. The club is official member of the German "RTA" which is the German amateur radio organization for talks with the authorities about ham radio.

QSL policy.

If you're member of an IARU member-club, you will receive my qsl card via bureau. However, I am a LoTW user so you can send me your qsl via LoTW, too.

Ham Spirit.

Two local amateur radio club members help me to bring up a vertical.

After I called for assistance, these two hams, Albert (DK2XD) and Kurt (DO6KF), immediately answered to help me. A few hours later the vertical was fully operational. 

Ham spirit is an essential part of our hobby.

QRO and QRP.

Sometimes when condx are good I switch off the high power devices and go back to the roots. That Kenwood TS-130V line is the fun part in my shack. 10 watts output from this nearly 40 years old line is enough even for some DX.

Ham Radio and Nature.

Two members of our local amateur radio club U24 of DARC, Albert (DK2XD) and Joe (DL4RDJ), on VHF fieldday. We use solar power when ever possible.

Picture is from our fieldday place near Pförring which is about 20 miles from my home.

Thanks to the mayor of the community of Altmannstein, who permitted us amateur radio at this place, we are active during contests on all bands.

RBN Skimmer.

My RBN skimmer is acitve most of the time on one or two amateur radio bands from 137 kHz to 30 MHz.

Receivers are homebrew SDR with Tayloe mixers and Si570 oscillators or SDR-IQ (see my webseite for more information). Decoding is with VE3NEA's famous CwSkimmer. An active antenna on top of the roof is used for reception.

Success of RBN network deeply depends on numbers of active nodes. More nodes worldwide would be helpful.

Dear visitor, if you are from Africa, South America, South East Asia, Oceania and Alaska / polar region, please consider installing a RBN node. It is easy. And it would provide hams worldwide with information about condx.


Vintage Equipment.

Here is my early YAESU F-Line, which was sold in Europe under the label of former Swiss/German radio company SOMMERKAMP.

The 1964 made F-Line was YAESU's early transmitter and receiver line with only electron tubes and without semiconductors/transistors (except some mixer diodes).

I use this rig for special events or sometimes just for fun.


My Home.

We live close to the autobahn A93 from Munich to Regensburg in a small village called Großmuß. The village has a population of about 500. It is part of the community of Hausen in the Bavarian district of Lower Bavaria.
